VEHICLE-"SEATe SPECIFICA'IIN forming part of Letters Patent No. 446,754,dated February 1?, 1891.`

Application filed December 16, 1890. Serial No. 374,866i (No model.)

' Texas, have invented a new and Improved Ve,

hicleSeat, of which the following is a speciii cation.

My invention is an improvement in vehicleseats, intended especially foruse in wagonseats, but which may be embodied in roadcarts, sulkies,the.; and the invention consists in certain novel constructions andcombinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a front elevation, and Fig. i? is a topplan, of myimprovement constructed for application to a wagonbody, theseat in Fig. 2 being removed and indicated in dotted lines.

In the construction shown the supportingframe is formed with the sidebars A A, having hooks a a to engage upon the top edges of theside-boards of a wagon-bodyand the con necting-bar B, which extendsbetween and rigidly connects the side bars A, as shown. To these sidebars A are journaled the shafts O, each having two cranks D, the cranksof each shaft being of equal length and proj ected radially in the sainedirection. The shafts are also so supported that the cranks D arearranged one in front and the other in rear of the connecting-bar B, sothat the said bar will not interfere with the motion of the cranks. i

The seat E is supported upon the upper ends of the springs F, theopposite or outer ends of which springs are connected with the wrists ofthe cranks D.

It will be noticed that each spring F extends from its crank Dinwardlypast the center of the seat and connects therewith on theopposite side of the center from the crankis preferred, because by itthe upper ends of the springs are secured below the plane of theseat-board, and a better action of the springs is consequently secured.

In the described construction of springs the movement or action ofonepair of springs controls the other and tends to preserve thehorizontal position of the seat, even when weight is unequally disposedthereon.

It will be understood that the improvements may be used on road carts,sulkies, rbc., in which case the shafts might be journaled in suitablebearings on the framing of such vehicles, said framing thus forming thesupport for the shafts in such use of theinvention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The improvement in vehicle-seats herein described, comprising theshafts, each having two equal and similarly-projected cranks, thesprings connected at their outer en ds with the said cranks and extendedinwardly therefrom past the middle of the seat and connected therewith,and the seat proper, all substantially as set forth.

2. The improved vehicle-seat comprising the seat proper, the blockssecured to the under side of such seat and arranged in pairs on oppositesides of the middle of the seat proper, the shafts having each two equaland similar cranks, and the springs secured at their 'outer ends to thecranks, extended thence inward past the middle of the seat, and securedto the blocks below the seat, allsubstantially as set forth.

3. The improved vehicle-seat herein described, consisting of the seatproper, provided on its under side with blocks G, the supporting-frameformed with side bars and the bar extended between and rigidlyconnecting the said side bars, the side bars being provided with hooksto engage the wagonbody and with bearings for the shafts, the shaftsjournaled to said side bars and provided each with two cranks, arrangedone in front and the other inrear of the connectingbar of thesupportingframe, and the springs secured at their outer ends to thecranks, extended thence inward and secured at their inner ends to theblocks below the seat proper, all substantially as and for the purposesset fort-h.
